Polarization‐Switching Controlled Luminescence in Hybrid Ferroelectric
Abstract
Abstract Luminescent ferroelectrics have sparked significant attention in integrated photoelectronic devices, optical sensing and storage. Their potential cross‐coupling effect of polarization‐light modulation would offer enormous possibilities for novel functionalities and multi‐level information processing. However, achieving controllable coupling modulation between photoluminescence (PL) and ferroelectric polarization has always been a long‐standing challenge since the first discovery of ferroelectricity in 1921. Moreover, the ferroelectrics equipped with tenably multi‐state emission in a single material has been a blank to date. Herein, we reported the first successful integration and coupling of ferroelectricity and luminescent behavior in a single‐component hybrid material, (Quinuclidinium‐3‐one) 2 ZrCl 5 . Remarkably, based on the controllable orientation of dipole ions, its PL intensity can be deliberately modulated by polarization switching under the action of external electric field, achieving a coupling‐induced PL intensity variation ratio as high as 50%, which is unprecedented among reported hybrid ferroelectrics. More interestingly, (Quinuclidinium‐3‐one) 2 ZrCl 5 also exhibits multi‐state emission with PL colors from apricot red to emerald green through varied light‐excitation. This work represents a major breakthrough in luminescent ferroelectrics and would herald the emergence of novel application potential toward smart photoelectronics.
